Electronic shifting is coming, weight is down, problems are fixed, PRICE IS HIGH, but it coming. Tour de France riders are using it, yes pro riders are finding this a reliable solution. The riders to look out for on the new Di2 include Columbia-HTC's Michael Rogers and George Hincapie on their Scott Addicts for the road stages, while for the time trial stages the entire team will ride Di2 equipped Scott Plasma 3 time trial bikes.
It uses batteries and while they are the crutch, if you let the battery runout while ridding you better be prepared to ride home in that gear, NO way around that!
Best of all you have controls for TT and Triathlons, right to the aero bars and off you go, not to worry about hills the buttery shifting makes going up hills easy and smooth.
